A maze of ducts run inside the walls and floors of your Winnipeg home. As the supply ducts blow air into the rooms, return ducts inhale airborne dust and suck it back into the blower. Add moisture to this mixture and you have a breeding ground for allergy-inducing mould, mites and bacteria. Many common filters can’t keep dust and debris from streaming into the air and over time sizable accumulations can form.
Pull off some supply and return registers and take a look at your ducts. Shorty’s Plumbing & Heating Inc. recommends duct cleaning when installing a new furnace. Many duct cleaners tout benefits like cleaner indoor air, longer equipment life and lower energy costs. A clean HVAC system will perform more efficiently and last longer, which may decrease energy costs and reduce the need for costly replacement or repairs. Cleaning has little effect on air quality, primarily due to the fact that most indoor dust drifts in from the outdoors. But it will get rid of the stuff that mould and bacteria grow on, and that means less of it gets airborne, a boon to allergy sufferers.
